I have the 3.2's with the Kharma Sub. I am currently driving them with the Lamm M1.2 hybrids, which were a replacement for the JL2. The CAT was a wonderful match with the 3.2's. But after a problem with the amp, and a poor response from CAT, I went out to GTT and listened to the Lamms. I can tell you that the Lamms do everything the CAT did with the addition of better control of the bass. The CAT does excel in this area, but it is a tube amp, and it just can't compete with the 1.2's. The highs are extended, and free of grain, and the midrange is just as smoothe. Asonicyouth is right in that Kharma does voice it's speakers with Lamm's. The synergy is obviously outstanding.
